为什么'pip show'或'pip list'对我不起作用？

Python的pip对于我来说可以用来安装和更新包，但是一些文档中的命令似乎不被支持（至少在OS 10.8.2和Python 2.7.2上使用1.2.1版本时如此）。当我尝试使用

pip list

或者

pip show

我得到的结果是

Usage: pip COMMAND [OPTIONS]
No command by the name pip 
  (maybe you meant "pip install ")

这些命令还没有实现吗（尽管已经在文档中记录了）？

它们在哪里记录？我的没有显示这样的命令：

hd1 % pip help
Usage: pip COMMAND [OPTIONS]
 --version                    show program's version number and exit
 -h, --help                   Show help

                              user@proxy.server:port then you will be prompted for a password.

你要寻找的新功能非常近期出现--它们在1.2.1.post1中出现，而不在1.2.1中，而你可能正在查看的文档（http://www.pip-installer.org/en/latest/）目前是用于1.2.1.post1的。

localhost-2:~ $ pip --version
pip 1.2.1.post1 from /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip-1.2.1.post1-py2.7.egg (python 2.7)
localhost-2:~ $ pip --help
Usage: pip COMMAND [OPTIONS]
Commands:
  bundle               Create pybundles (archives containing multiple packages)
  freeze               Output all currently installed packages (exact versions) to stdout
  help                 Show available commands
  install              Install packages
  list                 List installed packages (including editables).
  search               Search PyPI
  show                 Output installed distributions (exact versions, files) to stdout
  uninstall            Uninstall packages
  unzip                Unzip individual packages
  zip                  Zip individual packages

如果你想要它们，可以获取开发版本：

git clone https://github.com/pypa/pip.git
